Of course it's not subtle.
THIS is the pdf of the instruction manual for the MKH 800.
Look at the omni polar diagram on page 53.
If you use the microphone as end-fire you are 90-degreed off axis. You will see that you get a flat frequency response up to 8kHz - but it's -8dB at 16kHz and -18dB 18 32kHz.
Using it end-fire you lose the top end, but get the full frequency response from reflections from the walls.
The 90-degree frequency response curve is also shown on the frequency response graph (dotted line) as it shows the response on-axis (as a side-fire) and also at 45-degrees and 90-degrees off-axis.
*You* may like using it as an end-fire in your application and your acoustics - but *please* don't suggest using it like this to others, as it is incorrect use.
The polar-patterns and frequency response curves are published so users know what the microphone is capable of and what happens off-axis so they can make their own decision.
But the mic. is designed as a side-fire.
