Nope, SofTex on the SR5 Premium.
I think the seats are the same as far as contour between the SR5 & TE Premiums, but the colors are different. The TE Premium has all black SofTex with red stitching, SR5 Premium has two tone SofTex seats without contrast stitching (either black with grey inserts of beige with lighter beige inserts).
I've got a black SR5 Premium with the sand beige SofTex, and I think the interior is great. Looks much nicer than cloth and is easier to maintain (and should last longer) than leather.
