The samsung supports more video formats,has more apps in the smart tv platform,it also has a full fledged web browser that supports flash,where as the opera browser in the Sony doesn't yet support flash,it also lacks MKV support and doesn't support NTFS partioned HDD.
But what you do get in the Sony is a SPVA panel,where as the samsung D5500 do date the models i saw about 4 different showrooms had AMVA panel,slightly inferior viewing angle and black levels compared to the SPVA based tvs
So if media playback is a priority get the samsung,its image processing is on par with the Sonys,so it does have excellent SD picture quality.
If its a Sony then you could get it from the grey market,some places also sell the samsung and it should cost less then 50k.

Do note the IPS panels used in tvs don't always have higher color accuracy ,just because the IPS panels used in some pro monitors have better color accuracy doesn't mean its the same for tvs.
So saying a tv with ips panel has having better colors isn't true.Many times high end tvs with VA panels have better colors then high end tvs with IPS panels.
As far as viewing angle yes IPS based tvs have the edge for the most part,except perhaps when compared to some new VA based hybrid techs used in some really high end flagship models.
Update:the indian samsung D5500 may altogether lack a web browser
