I`m not sure if you could take a better look at anything through the spark plug hole than just using the green plug, but here`s a picture I took recently of the variocam, may give you an idea.
For reference, here is a picture for the size of the camera I used for inspecting the actuators, it`s a cheap Depstech camera from Amazon and it works with a smartphone.
And yes, this is only good for inspecting one of the small chain pads, the upper one, but this is the most likely to fail out of all the pads. For inspecting the long side rails I would lock the camshafts and crankshaft, pull the tensioners (to free up the rails) and the scavanging pumps and look into there with a camera. Wear is not likely on these at this mileage, but if one is broken at the pivots probably you will see it.
My bet is you`ll find the small pads worn down, did you see yellowish or brown plastic debris in the oil filter?
