Input color space tag in media pool

Sometimes I am lucky and the file(s) are read correctly but mostly not.

It's really helpful to know what settings were used on a shoot. Personally, colorspace info (gamma + gamut) is something I use to achieve better results, faster. I also like to do my own colorspace journeys for creative purposes.
Knowing the source is invaulable in that regard, taking the guesswork out of my job.

I thought I had read that Resolve 17 would be better equipped to read the color space tags in media files, but it doesn't seem so at the moment.

In Avid Media Composer, though AMA plugins, I get a lot of tags transferred from FS7 and color space info from C300 material.
But Avid is an NLE - why can't a color grading app import that same info?

Here in Avid we see that the footage is Canon Log3/Cinema gamut.
I work with a lot of mixed material shot by multiple photographers on the same show & timeline.
That means I could have Canon Log3 /cinema gamut, Canon Log2 / Cinema gamut and even BT.2020 from the C300MKII in the same sequence. Getting those tags from the native files would save me a bunch of time and headache.

Here in Resolve, we see some FS7 footage identified as s-gamut3.cine/S-log3, but not other native files, which are actually also s-gamut3.cine/S-log3. Why are some identified correctly, and not others?

Also, the last file is a C300MKII file in Canon Log 3 /cinema gamut (from the same card as above in the Avid bin)

Am I missing a way of importing footage where colorspace tags are correctly identified?

Agreed, this important missing information for colorists.
As well as the ability to import an ALE.
Assimilate Scratch has had this information exposed for years.
It's metadata, we shouldn't have to guess.
