Applying LARGErmfamilyscshapetextbf to entire title in beamer class

Question

I'm trying to apply LARGErmfamilyscshapetextbf to an entire title and rmfamilyscshapetextbf to an entire subtitle in the beamer class (see the minimal working example below). However, if I use {LARGErmfamilyscshapetextbf some title}, only the first letter is bold (see the picture below). If I apply LARGErmfamilyscshapetextbf{some subtitle}, only the last command gets applied, which is textbf or equivalently bfseries (see the picture below). This issue also appears in the comment and answer given below.
My question is: how can I apply all the commands, not only the bold one? In other words, how can I make the entire title LARGE, rmfamily, scshape, textbf, and the entire subtitle rmfamily, scshape, textbf?
Thanks for your help!

Not all font support bold and small caps. Try this.
% !TeX TS-program = pdflatex

documentclass[10pt]{beamer}

usepackage{amsmath}
usepackage{amstext}
usepackage{amsfonts}
usepackage{amssymb}
usepackage{array}
usepackage{graphicx}
usepackage{color}

usepackage{libertine} % added font

usetheme{CambridgeUS}

setbeamercolor{frametitle}{fg=blue,bg=blue!10}
setbeamercolor{title}{fg=blue,bg=blue!10}
setbeamertemplate{frametitle}[default][center]
setbeamertemplate{footline}[frame number]{}
beamertemplatenavigationsymbolsempty
setbeamertemplate{footline}{}
setbeamertemplate{headline}{}
setbeamertemplate{blocks}[rounded][shadow=true]

setbeamersize{text margin left=4em, text margin right=4em}
setbeamerfont{caption}{size=tiny}
setbeamerfont{title}{size=large}
%title[]{LARGErmfamilyscshapetextbf some title}
title[]{Hugesffamilyscshapetextbf{Some Title}}
subtitle{rmfamilyscshapetextbf{some subtitle}}
author[]{}
institute[]{}
date[]{}

begin{document}    
    begin{frame}
    titlepage
    begin{center}
    end{center}
end{frame}

end{document}

Now comment the line usepackage{libertine} and compile again.

The Computer Modern and Latin Modern fonts don't offer the bold/serif/scshape combination of font dimensions. The rmfamilybfseries and rmfamilyscshape combinations are available, but rmfamilyscshapebfseries is not.
If using the rmfamilyscshapebfseries combination is critical to you, you need to switch to a font family that provides this combination. Times (New) Roman is one such font family. Try running usepackage{newtxtext,newtxmath} before title{LARGErmfamilybfseriesscshape Some Title}.
