Mist presents and downloads them as full release versions.
one thing that distinguishes rc from release version is that a vm won't download ota if it is rc unless it is sequoia.

so if you have ventura betas/rcs as a vm and try to do an ota update to another beta or rc it won't work. you have to use the full installer to update.

on the other hand if it is a release version a vm can update ota.

in the case of 13.7 rc 1 i could not update my vm ota, which indicates that it is a rc not a release version. i used the full installer to update.

of course many times but not always the last rc has same build number as the release version and then a vm could update ota

but i don't think 13.7 has come out as a release version yet
 
Here is further evidence that 13.7 rc 1 is not release version yet

running this in terminal for ventura developer sucatalog:

Code:
for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-13seed-1.sucatalog | grep Info.plist | grep -Evw '(Info.plist.integrityDataV1|InstallInfo.plist)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
    curl -# $file | egrep -EA 1 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
    echo $file | sed -e "s/Info.plist/InstallAssistant.pkg/g"
done

returns this:

Code:
        Build
        22H121
--
        OSVersion
        13.7

but running this for ventura public sucatalog:

Code:
for file in $(curl -# https://swscan.apple.com/content/catalogs/others/index-13-1.sucatalog | grep Info.plist | grep -Evw '(Info.plist.integrityDataV1|InstallInfo.plist)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g); do
    curl -# $file | egrep -EA 1 '(>Build<|OSVersion)' | sed -e s/"<string>"//g -e s/"<\/string>"//g -e s/\ //g | sed -e s/"<key>"//g -e s/"<\/key>"//g -e s/\ //g
    echo $file | sed -e "s/Info.plist/InstallAssistant.pkg/g"
done

returns this

Code:
        Build
        22G830
--
        OSVersion
        13.6.9

And again the 15.1 people have to skip a beta update it seems... :(
