KODI 17 on Shield TV

Hi everyone,
I would like to thanks first the great work which is done on KODI 17.
It works like a charm on Nvidia shield TV Wink
I have two questions:
First: We can find KODI 17 on the playstore of the Shield TV and on the KODI website. 2 versions 32bits and 64bits on the KODI website and what is the playstore version ? as the Nvidia Shield has a 64bits chip and 64bit android version, I think it will be bettre to use the KODI 64bits version no ?

Second: Do you think it will be possible to add some scaler settings like lanczos 3 optimized or others/better soon ?

Thanks again
Regards Wink
