Actually, I said 'relatively' new? OLED is still in its early generation. There are questions of OLED longevity as it uses organic based LED which reportedly degrades unevenly over time, part of the problem. Some manufacturer released firmware have also resulted in known loss of brightness by users in some display modes? The next generation of OLED is coming as early as this year, and should address some these issues with earlier models.
So, yes, my recommendation was to wait and instead went with a solution that was near comparable, along with high-brightness (>750 nits) 4K display which was his preference. In any case, the U.S. taxpayers are paying for it.
