I'd more be afraid than happy if a TV were to support that (and even more if laptops would use it to bridge a TV to the home network), simply because a TV that has internet access in any kind will download ads and nagware and upload viewership statistics in return.
Modern TVs truly have become like 1984 - there is no way a 4k 60-inch TV at 340€ is anywhere close to profitable on its own without milking the user's data for all it is worth. The actual cost of a TV is more like 900€+ if you go by the prices for "digital signage" TVs.
