I was just having a look at The Open Group official register of UNIX Certified Products, and it doesn't list any system to be registered for the UNIX V7 brand.
Nevertheless, I did remember that Oracle Solaris was announced to have achieved the certification:
We are pleased to announce that Oracle Corporation has achieved certification to the UNIX V7 Product Standard for: Oracle Solaris 11.4 Operating System and later on SPARC-based and X86 based platforms

This tweet dates back to August 2018. Still, as of now, no update has been made to the register.
Is this just due to delays and bad maintenance of the site?
Do you know any other infos regarding systems that have reached compliance for the UNIX V7 brand?

The Open Brand Register entry for Solaris can still be found on the web site, and still appears in some search results, but presumably it hasn’t been renewed, which is a requirement for products to continue to be listed.
It did appear in the register after the announcement, so its absence isn’t due to a lack of updates — rather, it was added to the list, and then removed again. (This applies to a large number of certified products.)
So there is no currently-registered UNIX V7 certified operating system, but there have been in the past.
