Common for the oil cooler in the middle v to leak. Typically it fails internally, leaks and fills the v before spilling over. Less common is rear cam seal.
Disco 3 MY09 is leaving it's mark on my garage floor. Rear of engine somewhere up high not main crank shaft oil seal. What are the likely causes please.

During recent coolant change noticed oil gathering in front of gearbox bottom of bell housing above the sway bar.
Small enough not to drip on garage floor yet but more noticeable than last time I was underneath.
Clearly coming from above at back of engine down drivers side dripping over EGR and fuel cooler.
Suspect oil cooler or part of the engine breather system.
When changing the oil filter last time looking into the pocket with filter removed it’s pretty grimy around there.

How quickly are you pouring your oil back in. ? Could it be filling up the rocker cover and leaking oil the back? When mine leaked it dripped onto exhaust crossover and smelt of burning oil so may be different to your issue

If it’s only after a filter change:
Don’t crack it too soon after the engine has been run.
Wait 5 minutes and then do it.
I crack the filter loose, then go under and fit my drain line, as it starts to slow the flow I pull the filter and replace.
Be careful to keep the filter vertical as you lift it or a heap of oil will empty into the valley! Other than that you won’t drop more than a a few drops.
