Do not contain at feed server ? Um, it is possible because the DM800 HD device has a very little flash memory. So even the feed server or OpenPLi-7.2 image for this device will not include ServiceApp. Powerful hardware is also required, which unfortunately the old DM800 HD is not. ServiceApp uses ffmpeg and ExtEplayer3, which require some better hardware. Rather, this will be why they were not included in the OpenPLi 7.2 feed for your DM800HD.
You need to use an flash expander that extends the flash memory to the USB stick. This is not reliable, but at least the plug-in folder should be transferable to a USB stick. There is a symbolic-link, referring to the USB stick empty directory. Of course, the USB stick must contain the Linux file-system (ext2, ext3 or ext4).
If you would like to play with it, here you have current download links:

Install these packages in the same sequence.
Again, note that you should use a flash expander and do not guarantee proper functionality, as the DM800 HD hardware is weak and old (300MHz mipsel CPU).
/////// EDIT :
Unfortunately, I found out that ServiceApp installation package also contains a binary file. It will probably not work on another chipset (a different decoder found in your set top box). This binary file will probably be bound not only to the processor type I thought (mipsel) but will also be bound to the chipset type (decoder type).
