I suggest to you reading:
TVs are all awful

as well as the linked postings
Why EDID is not trustworthy for DPI

And then just stick to setting the resolution *manually*.
I know the latter are related to DPI and thus also how TVs report physical
size. But at least in the Blog by Matthew Garrett are also hints, while
resolutions would not be reported correctly.
The actual implementation as well as partly also specification for DDC
appears to contain quite some crap it seems. Manufacturers of TVs do not
seem to care much about reporting correct values in order of cheap, cheap,
cheap.
That is at least what I gathered from above mentioned reading.
