Have you asked fabricator? Pictures do not really show much in my opinion and I do not see how the properties of a painted metal railing indoors can change much.

You should also check the local code if your railing doesn't need a return to a wall.

R311.7.8.4 Continuity

Handrails shall be continuous for the full length of the flight, from a point directly above the top riser of the flight to a point directly above the lowest riser of the flight. Handrail ends shall be returned or shall terminate in newel posts or safety terminals.

Exceptions:

1. Handrail continuity shall be permitted to be interrupted by a newel post at a turn in a flight with winders, at a landing, or over the lowest tread.
2. A volute, turnout or starting easing shall be allowed to terminate over the lowest tread.
