It's hard to actually show ROI from any programming methodology or tool. You can show ROI from a product or feature, but the tool/methodology is a multiplier on the velocity of creating that which is not directly observable.

It's really not. When we switched from CVS to SVN I had to show ROI and when I we switched from SVN to git I had to show ROI and when we switched from Ada to Java I had to show ROI. When we switched from Xen to KVM I had to show ROI and when we switched from PAM realtime privileges to rtkit I had to show ROI. When we switched from chroots to LXC I had to show ROI, when we switched from LXC to docker I had to show ROI, and when we switched from docker to podman I had to show ROI.
If you can't show ROI there's literally no reason to ever switch anything.
