LG V30 units on T-Mobile has just started receiving their Oreo serving. There's, however, a caveat - the update is not yet rolling out over-the-air. You'll have to manually install it through the LG Bridge software. There's another way to get the update (if you wanna go down that route): download the package from XDA and install it on your device using LG UP. An official change-log isn't yet available, but going by the same update on other carriers it should include AI features from the V30 ThinQ, as well as the 'ThinQ' branding. Oh, and yes, the screenshot makes it clear...
