P: Support for Canon .CR3 Camera-matching Profiles

I'm still not seeing these profiles in LrC.  Are these "Color Fidelity" profiles what you mean by Camera standard?  And when will they be available in LR?

Third party camera matching profiles have just been released for 1DX Mark 3: Camera Standard, Portrait and Low/Medium/High general puropse profiles. They appear to work well and are much improved from Adobe Color renderings.
Not sure if I'm allowed to post the link here or not.

Referring to Camera Matching Profiles. 

Adobe has always supported camera profiles, as well as lens profiles.  One of the benefits of using the subscription is that you have access to these updates.  The issue is they haven't kept up with the profiles of the latest Canon bodies. All of my other Canon bodies are supported (1DX2, 7D2, 5D3, 5DSR) - it's only the latest model that isn't supported.  I don't believe it's unreasonable to expect that Adobe supports the latest camera profiles.  

I've got two different Canon bodies and both Adobe supplied and better custom built profiles. NOT all cameras Canon or otherwise have Adobe Camera Matching profiles and Adobe never promised this.
Edit: LR and ACR have never supported ICC camera profiles if that's what you mean.

No... I think you are misunderstanding or are clearly mistaken... the only optional for color profiles are Adobe color, adobe standard etc. There are no "camera standard" and so on profiles. As with pretty much all the other available camera bodies...

I'm not sure what you mean that it supports profiles.  The issue is that it doesn't support Canon .CR3 profiles.  There are other profiles like Adobe and yes, you can make custom, but many times the Camera manufacturer profiles are quite useful.  

Other Canon formats like .CR2 are supported.  Not sure why .CR3 isn't supported.

It not only ”supports” profiles, you can and often should make your own custom profiles.

I'm having this same issue.  The 1DX Mark III has no supporting camera color profiles.   Adobe team, any news on when this will be supported?  This is Canon's flagship new camera - it's hard to believe that your program doesn't support the color profiles.
