Is mastering for 4K HDR very expensive? Possible for lesser known titles?

I'm fine waiting 10 years for all these titles to trickle out. I'd hate for whiny internet "demand" for HDR passes and 4K scans to be responsible for crappier standards than the Sony, Paramount and Warner Bros. level of output we've seen thus far.

Hopefully there is an internal understanding in these companies home video departments that quality control is an important aspect of this format, given it's niche status as it is.

Anyways. There is a lot of industry info that the cost of these is a minimum tens of thousand per title.
