The matte antiglare coating adds a noticeable texture to uniform areas of the screen, making it less clear compared to the glossy LG UltraFine and Apple Studio displays. I’d much rather have a glossy option to avoid this texture.
and the anti-glare coating really started to bother me the more time I spent with it. At first I thought I was going to get used to the AG, but in comparison to the ASD it just looked like a dirty screen and it reduced the sharpness.
It will be interesting to see what the upcoming Samsung 27" 5K will be like. Samsung claim to have come up with a more advanced antiglare coating ("UL Matte Display Technology"*) which they used on a couple of recent monitors, and I would assume might use on the 5K.

Also, personally I have a matte 24" 4K 185 ppi monitor at work, and a glossy 24" 4K 185 ppi Ultrafine at home. The glossy is definitely sharper for text, but the matte is still very comfortable in moderate lighting. In fact, perhaps it is "softer" on the eyes. One thing to note is that matte monitors actually lose contrast very quickly in bright environments as they have to do more scattering of incoming light. - maybe try repositioning your lights. I always aim to place my desk in the darkest corner of the room, with the user facing towards the window.
