Difference in front cameras between 2017 and 2018?

[teethdood]

Long story: two model Xs got Xpel wrapped, both started developing the Autopilot Limited issues. Tesla confirmed that the front cameras (by the fenders) are acting up. I talked to the detailer and one good possibility is that the cameras got switched when they were taken out in the wrap process. The detailer is going to play with the combinations to see if the problem goes away. Cars are in the shop.

Short question: Do you know how to tell between 2017 front cameras and 2018 front cameras? Are they the same? It looks like they have the same part number written on the outside.

In cars made before Aug 2017 (hw2.0) the front cameras have RCCC color filter. After that (hw2.5) the filter is RCCB. IT used to be that autopilot software did not care, but late in 2017 an assertion was introduced to ensure a perfect match. Use the service diagrams to see what part number got on hw2.0 and what goes to hw2.5 to save time shuffling the cameras around (perhaps somebody could list the partnumbers here, or perhaps it's already on epc in open access?)
