It's BOE panel probably. We are screwed since they're inserting these almost anywhere these days. In my region it's a struggle to find a mobility ASUS laptop without either OLED or BOE. I am struggling myself as I wrote in another post.
What's worse I cannot find any objective measurement that would prove to me that BOE panel is bad. I look at my older laptop with Innolux and newer with BOE side to side and barely can see any difference in rendering. Yet after hours of working on older laptop I am fine, but the latter gives me eye strain. More specifically, when I start working on a BOE panel, it's fine. But after some time of reading text it becomes blurry , while white background becomes too bright. It's like it's pushing on your eye balls. Hard to explain.
My panel is NV156FHM-N6E.
I can only recommend trying to get a Zephyrus with Innolux panel. I know they made G15 with these - see e.g. https://www.notebookcheck.net/Asus-ROG-Zephyrus-G15-laptop-review-Eye-catcher.517789.0.html. This one got an 165 Hz WQXGA Innolux panel. This one should be good.
There is a G16 which apparently has 240Hz Tianma panel: https://www.notebookcheck.net/Asus-ROG-Strix-G16-G614JZ-laptop-review-Clear-the-stage-for-the-RTX-4080.701775.0.html. It's a Strix but I've zeen Zephyrus with exactly same panel characteristics out there, hence probably the same panel.
I am not sure how good for eyes Tianma panels are. Maybe someone on this forum could advise.
To be quite honest I am desperate enough that I am considering to resort to of these Zephyrus models even though it's a drastic overkill for my working goals just because of the screen.
