Delta shower valve trims - logo change

[Pink Jazz]

We have a Delta Lahara valve trim that we will have to drill out the set screw. We are replacing it with a Delta Classic (with lever handle).

I noticed our new Delta Classic trim has an all caps sans serif Delta logo, while our old Lahara and the image of the Classic trim online has an italicized mixed case serif Delta logo.

I wonder, approximately when did Delta make this change to their valve trims to the all caps sans serif logo? It must be pretty recent.
