It is important to consider that no current TV has a glossy screen except the high-end Samsung's QLED and Sony/LG's OLED.
A glossy screen is required to make the colours pop and enjoy watching for a long time without eye strain. They can still have some light coatings to avoid glass-like full reflections without making the picture dull.
However, only these high-end TV's have glossy screens. But people end up paying such high-end prices of over Rs.1.5 lacs for plain LCD TV's (there is no LED TV, it simply means that the backlight is LED) with a semi-gloss coating on the screen.
CRT TVs and monitors of any budget in the old times never had such coatings on them.
I understand that it does not bother everyone, but I cannot stand a non-glossy screen. Even my PC monitor is glossy.
It is, however, not just my own opinion, as TV manufacturers also know this and charge a premium for glossy screens.

(Samsung's LED-LCD TV models starting "Q" are from their costlier QLED line)
Here is how I test the glossiness of the screen.
Whenever you go to a store, throw a flash-light from your mobile phone at a turned off TV or on the black parts of the image on the TV. If the reflection of the flash is sharp with clear edges and takes just as much area as the actual flash, as if it was a mirror, then it is quite glossy. If the reflection is muted, or made dull and spread out over a larger area, then that is a semi-gloss finish and the more dull and spread-out the reflection, the more the coating on it. And that dullness is what your eyes will see even if you don't notice it all the time.

If there is a semi-gloss coating, then it should be minimum. But I have seen very harsh coatings, even on many Sony TVs. While they look good in the showroom which has many overhead lights, they look awful in your home where there are less lights and you can control which ones to keep on and you can also cover your windows with drapes to avoid direct reflections.
We can start making a noise about it in the showrooms and on various forums and social networks till it reaches the manufacturers. Even medium range TV's should have glossy screens, or at least an option for those who can control the lighting in their rooms to see the best quality of the picture. And I would never pay a premium price for a non-glossy screen. Vote "no" by not giving your money to them for such models with heavy semi-gloss coatings on them.
