I am confused. Is it a defective monitor, or what is it? acer nitro xv275k p5

So I bought this monitor about two months ago(acer nitro xv275k p5), and while my room's lights are turned off, I have noticed that the panel is glowing, just like an ordinary, cheap IPS panel with a disgusting amount of backlight bleeding. As I don't have much knowledge of mini-LED panels, I bought it just because it was advertised as a mini-LED, and I also have a MacBook M4 Pro, which also has a mini-LED panel, and the darks are just like OLED. Now I contacted Acer customer care, and they told me there is no dedicated dimming zones on/off option. If anybody can tell me what's wrong, I will be very appreciative. I am attaching both my macbook's panel and the monitor's panel and both are turned on.

The glowing effect on an Acer Nitro XV275K P5 monitor is likely caused by a combination of IPS glow and the monitor's Mini-LED local dimming features. While this is a normal characteristic of the technology, there are steps you can take to manage and reduce it.

1. Adjust monitor settings:-
Lower brightness: The glowing effect is more pronounced at higher brightness levels. Lowering the brightness to a comfortable level for your environment will significantly reduce both IPS glow and blooming.
Turn off local dimming (HDR): For normal desktop use, disable local dimming in your monitor's on-screen display (OSD). This will prevent the blooming effect that occurs with dark text on a light background. When gaming or watching HDR movies, you will need to re-enable local dimming for the best picture.
Change display mode: Experiment with the monitor's built-in picture modes, as they can have different brightness and contrast presets.
Use bias lighting: Placing a light source behind your monitor (known as bias lighting) can help your eyes perceive better contrast and make the glowing effect less noticeable.

2. Change your viewing environment:-
Increase ambient light: Using your monitor in a moderately lit room can reduce the visibility of IPS glow. The contrast between the screen and a dark room makes the glow more apparent.
Change viewing angle: Sit directly in front of the screen. IPS glow is more visible when viewing the display from an angle.

3. Test for hardware issues:-
Test for backlight bleed: While IPS glow changes with your viewing angle, backlight bleed is a uniform bright spot or cloud on the screen that does not change with your viewing angle. To test for this:
Go into a dark room. Display a completely black image on the monitor. If you see uneven, static light leakage that doesn't change when you move your head, you may have a manufacturing defect.
Contact Acer Support: If you believe the glow is excessive, persists after adjusting settings, and is not just typical IPS glow, you should contact Acer for support. If the monitor is new, you can also consider returning it to the retailer for a replacement, as the severity of these effects can vary between individual units.

Yes, backlight bleeding can occur in mini-LED displays, though the technology aims to reduce it by using thousands of tiny, precisely controlled LEDs for improved local dimming. Like other LED-backlit LCDs, mini-LED screens can suffer from light leakage from the edges or corners, appearing as bright spots on dark backgrounds, due to factors like manufacturing defects, poor assembly, or physical damage.

Improved Local Dimming: Mini-LED technology features a much higher density of tiny, precisely controlled LEDs compared to standard LED TVs.
Better Isolation: This advanced dimming allows for better isolation and control between different "dimming zones," meaning light can be directed more accurately where it's needed and blocked where it isn't.
Reduced Bloom and Bleed: The increased precision in controlling light can significantly reduce or even eliminate issues like backlight bleed, resulting in deeper blacks and a more immersive viewing experience
