Hope so, I personally won't. Principle of patch is precisely to let TV think it's always in fullHD (->fit to screen available), so it has some sense (even if unexpected) strange things could happen on UHD where it has absolutely not been thought for, nor tested, nor known to E where I first implemented it. Now we basically have "1 byte patch" and what you're looking for is contents analysis and so on...
Would need totally new and specific lib for very marginal case: rare HU for rare UHD channels, in case I didn't stop developing for pre-Tizen TVs anyway.
Also hoping 4K won't be future like 3D and curved screens were
(given that most people already can't see any difference between DVD and Bluray...)
Btw, wondering how you can use H lib without being donor to get H root
