....My original question was, what the difference was between my matte SS CZ-75B and a CZ-85B. So far, it appears the answer is, my 75B does not have an ambi slide release, although it does have an ambi safety.

I pulled this from Wikipeda:
CZ variants of the CZ 75 include:
CZ 75
The original CZ 75, easily identified by the heavily stepped slide and short slide rails
CZ 75
Late version, easily identified by longer slide rails and shorter slide-step
CZ 75 B
Second-generation CZ 75, upgraded with an internal firing pin safety, squared and serrated trigger guard, and ring hammer
CZ 75 BD
A variant of the now-common CZ 75B (B standing for firing pin block) with a decocker replacing the traditional manual safety. (D stands for decocker.) This variant is quickly becoming the most common of the CZ 75B models, due to the additional safety the decocker safety provides.
CZ 75 BD Police
Variant of the CZ 75 BD equipped with loaded chamber indicator, reversible magazine catch, lanyard ring, checkered front and back strap of the grip and serrated trigger as standard. Most Police models have "Police" stamped on the slide. A smaller amount exclude "Police" but have front slide serrations.
CZ 75 B Stainless
Stainless steel version of the CZ 75 B. Available in a high gloss and matte stainless finish. Also available in the new/limited edition (sand blasted finish with sides of the slide and frame decoratively ground). All stainless models feature ambidextrous safeties.
CZ 75B Omega
A version of the CZ 75B with a factory-reworked trigger group. It is available chambered for 9 mm or .40 S&W
CZ 85
An updated version of the CZ 75 that is also ambidextrous
CZ 85B
A CZ 85 with a firing pin block
CZ 85BD
A CZ 85 B with a decocking lever, instead of a safety
CZ 85 Compact
A limited production compact CZ 85 with under-barrel accessory rail and chambered in .40 S&W. Identical to the current CZ 75 compact in .40 S&W.
CZ 85 Combat
adds an adjustable rear sight, extended magazine release, drop-free magazine and overtravel adjustment on the trigger. Lacks a firing pin safety so that firing pins can be replaced without special fitting.
As you know, the CZ 85 has both; an Ambidextrous Safety and Slide Release
The Stainless Frames are based on the 75B-SA Frames
Kinda odd that the
B-SAs weren't designated an "85"B-SA
