Input latency is great after the updates they implemented early this year. I have a 65B6 and a 55C6. Guests still complement them even after a year of ownership.Oh, I've seen some LG OLED panels at stores before. Those things look top-notch. I just haven't had an opportunity to test their input latency, and LG's already left a bad impression from what's probably decade-old equipment by now. I hope they've improved, because input lag is something that most HDTV manufacturers frankly don't seem to care about when computer monitor usage and gaming seem to be completely secondary to movie/video content.
As for having top-notch TVs and screwing up phone panels, how 'bout we invert this a bit, since Samsung is in the exact opposite situation? Class-leading OLED panels on phones, and yet their HDTVs are basically LCDs with fancier branding now, outclassed by LG's offerings.
I think part of it has to do with their particular implementations of OLED display tech; LG uses white OLEDs with color filters, which isn't very power-efficient from a smartphone standpoint. Samsung uses proper colored subpixels, which results in the blue ones aging much faster and the whole thing being even more prone to burn-in in the long run for HDTV and especially monitor use.
