I have a ThinkPad T14 gen 1 from work with this panel:

and it's great, no issues at all.
I also have T440s as a personal laptop and it's been great for the last 4 years with this panel:

Recently I'm on a hunt for new personal laptop and I think I had some BOE panel on X1C6 which had 6-bit color depth with 2-bit FRC and it caused some light headaches for me, I've returned it. Also T490 had some ChiMei 8-bit panel that gave me some weird feeling that it won't be alright in the long run, also returned. Right now I'm looking to buy another T14 gen 1, maybe I'll be lucky and get a good panel.
