Rovers went into the Eastlands clash aiming to avoid a third successive Premier League defeat for the first time in almost two years under Sam Allardyce.
Having preserved that record, Samba is now looking for Blackburn to turn good performances into victories, starting at home to Fulham on Saturday.
He told Rovers Player: "It's very encouraging. There's been a massive improvement in our heads since last season.
"We finished very strongly last season and we tried to bring that into this season. We knew we played well but we didn't win, and we knew at some point the luck would turn a little bit in our favour.
"We've started with a point and now we're looking for nothing but three points from the next game then continue from there."
