When I mention increase in Lab B, it's for the full, diluted Eb6 type inkset, not just the 100% K or Black Only ramp. 100% K or BO ramp variances are too close to the noise/maximum accuracy of the spectros we use to do an valid comparison of 100% K reads done with different units.
However, a fully diluted Eb6 inkset printed on a Epson Hot Press natural from your 3800 should produce ramps that, even if not identical numbers, will be quite congruent if similar printers are used. My 7800 and 9800 should be close enough to your 3880 for this purpose. A comparison of those results might tell us if we have the same ink or not. Both of my current "Eb6" type inksets/printers used the Eb. v. 1.1 (actual STS sourced) starting inks. I dilute my own with C6b. That and the MIS dilution base look the same. If you provide the full LAB numbers for your dilute "Eb6" type inkset, I'll see what I have that is close. Specify the full settings on the driver or QTR. I always use the highest quality possible.

Yes, your values are sufficiently close to keep consistent results from a batch to another without huge adjustments.
On the K ramp, the LAB B values I obtain with v1.1 are equally more high than original Eboni, but it's really slight. Nearly similar on Canson Rag (on average : +0.2), a little more noticeable on HPN (+0.5).
The prints are made on a 3800.
